For several years now, we have been adopting a BIM approach for our construction studies, particularly through the use of digital models. Convinced of its usefulness, we wanted to use these models and all the information embedded in them for the benefit of our construction teams, as close as possible to our sites. We therefore turned to NEXT-BIM, who first supported us during a test phase, then in the deployment phase. Today, NEXT-BIM is a tool that our site managers would not do without and that allows us to take a step forward towards the digitalisation of our business. All of this is in addition to the time saved by the tool: installation of equipment and reservations without a plan, checks and controls on the networks installed, the placing of reservations and finally, the recalibration of the model on the real thing!
